Scientists create first billion-atom biomolecular simulation

Posted by in categories: biotech/medical, genetics

Researchers at Los Alamos National Laboratory have created the largest simulation to date of an entire gene of DNA, a feat that required one billion atoms to model and will help researchers to better understand and develop cures for diseases like cancer.

“It is important to understand DNA at this level of detail because we want to understand precisely how turn on and off,” said Karissa Sanbonmatsu, a structural biologist at Los Alamos. “Knowing how this happens could unlock the secrets to how many diseases occur.”

Modeling genes at the atomistic level is the first step toward creating a complete explanation of how DNA expands and contracts, which controls genetic on/off switching.
